Actually, I sort of like Bristone, because damage reduction is in my opinion the best type of bluff. I'm thinking of saving for Toro and swtiching it for Rolph, which will net me an extra star, but it's all still undecided. I think I should focus more of the Piranas side because the GHEIST one is decent.

When I made this post I was hoping to find out what those stats used to be. Maybe in the case of Melluzine and Lunatik a case can be made to go back to their original stats now that stronger cards are out.

Xu52: It has a ridiculous amount of damage and the ability forces your opponent to pill up. The downside is for 5 stars it is a lot of deck space to use on what is essentially a bluff. Whilst he can be used to power though 6 power doesn't cut it for a big hitter.

Now for the de facto best Gheist cards:
Zero Dead: With 7 power and 4 damage and any ability based soas blocked, what's no to like. When this only costs 2 stars he prooves to be one of the best fillers in the game.

Leviatonn: The big daddy and best Gheist card, for 3 stars you have full stop, decent damage and since many cards now are ability dependent for their high power, you can often have higher power to.

Toro/Methane: 9/5 or 7/7 depends on your personal preference which you want and on your individual deck needs, more seem to like Methane, but since Gheist does have room for both so why not. why not .

The other bonuses include attack+ or-, power+ or -, damage + or -, Stop Opponent Ability/Bonus, or Poison. the cheapest cards will probably be fang pi clang cards (damage plus), and they might go well with your power plus. that's all i got.

Lehane (U), Marlysa Cr (Cr), Hawkins (U), Gil (U)
but all of this card is really gonna be strong with their bonus
Lehane (U) with + 8 attack and SOB is very scary
Marlysa Cr (Cr) with +2 damage is 7/4 wth SOB
Hawkins (U) is only ordinary 7/2 with -2 pillz min 1 without his SOB bonus
same with Gil (U) that without +8 attack

@guolin:
replacement means subtitute card
vladimir is a replacement for XU52
that means, if you don't have XU52, you can use vladimir

if you say, XU52 is a replacement for vladimir, that means, if you don't have vladimir, you can use XU52 (strange isn't it?)
leviatonn is very good, try to buy credits, and open danger pack, maybe you will get one
or, you can get 1 credit per tournamnet if you enter top 1/3, 20 tournament, and you can open 1 pack
